8 Signs Your Dog May Have a Urinary Tract Infection

bacterial urinary tract infections in dogs


  • Urinary tract infections (UTIs) are relatively common in dogs, and E. coli is the culprit in about half of all canine bacterial UTIs
  • UTIs are usually the result of a change in a dog’s immune defenses that allows bacteria to proliferate and persist in the urinary tract
  • There are several symptoms that occur with UTIs in dogs; a urinalysis is required to confirm the diagnosis, and a culture and sensitivity test is needed to check for the presence and type of bacteria involved
  • The biggest reason UTIs do not resolve is the wrong antibiotic is selected and/or the length of therapy is inadequate
  • To prevent UTIs in your dog, it’s important to monitor urine pH levels and feed a low-carb, starch-free, nutritionally balanced, species-appropriate, preferably fresh diet
